摘要

•Single-phase flow on helical corrugated tubes of different pitch.•Measurement of pressure drop and heat transfer characteristics.•3D CFD model simulations in the transition from laminar to turbulent.•Model successfully validated against experimental results for all tested tubes.•Model allowed phenomenological interpretation of enhanced thermal performance.
